Was just thinking about Cavani and Gotze.
Cavani is the highest plaid player in the history of his team, and is pretty much guaranteed to play with them in the Champions League next season. Gotze's team will likely be in Champions League next season. They play in front of a massive, adoring crowd, and have just won the domestic league.
Why would either one of these guys come to Arsenal in the absence of an ambitious Mansour/Abramovich style project?
